Every one of them has an even number of factors.

No. They have different number of factors

12 is an even number and it is also a composite number because it has more than two factors

For a number to be prime, it must have factors, or numbers that go into it, other than 1 and itself. Since 2 goes into every even number, almost every even number is prime. One exception: the number 2. This is because two's only factors are 2 and 1.
